The Subjunctive I in German: What is it and how to use it?

In German, the subjunctive I is used mainly in written language to report what someone said or did while allowing some uncertainty about whether what they said was true. You’ll see a lot of the subjunctive I used a lot in the German news, whether you read newspapers or listen to podcasts. For example:

Subjunctive 1

Taylor Swift sagte, sie habe hart an dem neuen Album gearbeitet.

Taylor Swift said that she worked hard on the new album.

In this article, we'll take a closer look at the subjunctive I (Konjunktiv I) in German. We’ll go through how to form it in different tenses, how to use it, and discuss some cases where you should use other forms of the verb instead. Let’s have a look!

    The German subjunctive: Subjunctive I vs. subjunctive II

    In German, there are two verb forms that we call “the subjunctive”: the subjunctive I and the subjunctive II. Both used for the same broad purpose: to show some level of speculation or uncertainty about whether an action happened, will happen, or is happening.

    In most contexts, you’ll probably use the subjunctive II. It’s more common, less formal, and can be used in a wider range of situations.

    Experts say that interest rates will fall this year.

    If you translate “will fall” using the subjunctive I, you can make it clear that you only have the experts’ word for it: you have no information yourself. It’s like saying “apparently interest rates will fall.”

    So, though the subjunctive II may be more common, it’s important to learn to form and use the subjunctive I as well!

    Tip

    Remember that “normal” non-subjunctive verbs are called “indicative” verbs. We’ll use this term below, to contrast these two moods.

    How to form the subjunctive I in German?

    The rules for forming the subjunctive I depend on the tense of the verb. You can use this mood in the present tense, past tense, future tense, and future perfect tense. The ones that you will come across most of the time are present and past, but we’ll still take a look at how to form all four of them.

    Subjunctive I: Present tense

    To form the present tense in the subjunctive I, you’ll just use the regular present tense verb endings (-e, -st, -t, -en, -t, -en). The only differences are:

    • you’ll add an -e between the ending and the stem in the “you” forms (du and ihr)

    • the ending of the er/sie/es(he/she/it) form is just -e (not -t)

    Compare the present subjunctive I and the present indicative of the verb machen(to make, do)

    Present tense
    Subjunctive I
    Indicative

    ich mache

    ich mache

    du machest

    du machst

    er/sie/es mache

    er/sie/es macht

    wir machen

    wir machen

    ihr machet

    ihr macht

    sie/Sie machen

    sie/Sie machen

    For example:

    present subjunctive 1

    Harry sagte nach der Schule, er mache jetzt seine Hausaufgaben.

    After school Harry said he was now doing his homework.

    Note that sometimes the present subjunctive I is translated using the English past tense. We’ll talk more about that below!
    Exception!

    This conjugation rule applies to all verbs except for–you might have already guessed it as this one is usually the odd one out – sein(to be). Take a look at its conjugation table below.

    sein(to be)

    ich sei

    wir seien

    du sei(e)st

    ihr sei(e)t

    er/sie/es sei

    sie/Sie seien

    Note that in the “you” forms (du and ihr) the -e- is optional. The forms with the e are a little old-fashioned, but you can still come across both versions today.

    Subjunctive I: Past tense

    The past subjunctive I is pretty straight forward. You use the subjunctive I form of the auxiliary verbs haben(to have) or sein(to be) and the past participle.

    haben / sein
    present subjunctive I

    past participle
    main verb

    Harry sagte, er habe laut über Rons Witz gelacht.

    Harry said he laughed hard at Ron’s joke.

    Harry sagte, er sei gestern zu Hagrid gegangen.

    Harry said that he went to Hagrid’s yesterday.

    By now these pieces are probably familiar to you, but if you need to review, check out our posts on choosing between haben and sein and on past participles in German!

    Let’s look at a couple examples: lachen(to laugh)and gehen(to go, walk).

    lachen(to laugh)

    ich habe gelacht

    wir haben gelacht

    du hab(e)st gelacht

    ihr hab(e)t gelacht

    er/sie/es habe gelacht

    sie/Sie haben gelacht

    gehen(to go, walk)

    ich sei gegangen

    wir seien gegangen

    du se(e)st gegangen

    ihr seiet gegangen

    er/sie/es sei gegangen

    sie/Sie seien gegangen

    Subjunctive I: Future & Future Perfect

    When you form the subjunctive I in the future or future perfect, you’ll need to use the present subjunctive I form of the auxiliary verb werden(will, to become)

    • Future Subjunctive I:

      werden
      present subjunctive I

      infinitive
      main verb

      Harry erzählte mir, er werde am Montag seinen neuen Besen bekommen.

      Harry told me that he would get his new broom on Monday.

    • Future Perfect Subjunctive I:

      werden
      present subjunctive I

      past participle
      main verb

      haben / sein
      infinitive

      Harry erzählte mir, er werde bis Montag seinen neuen Besen bekommen haben.

      Harry told me that he would get his new broom on Monday.

    For reference, please see a full conjugation table of werden(will; to become) in subjunctive I below:

    werden(will; to be )

    ich werde

    wir werden

    du werdest

    ihr werdet

    er/sie/es werde

    sie/Sie werden

    When to use the subjunctive I in German?

    In German, you’ll most often use the subjunctive I in indirect reported speech, particularly in writing.

    Indirect speech is used to report on the message of what someone said or thought, without necessarily using their exact words. An example in English might be, “Marcus said he wasn’t coming.” Notice that we understand that Marcus literally said something like “I’m not coming,” but here we aren’t reporting his exact words, so this is indirect reported speech.

    In German, indirect reported speech involves two parts:

    • a main clause, containing a verb of reporting sagen(to say), berichten(to report), or erklären(to explain).

    • a subordinate clause, containing the reported speech.

      → in writing, this verb is in the subjunctive I!

    Let’s look at an example. Let’s say you’re a reporter and you hear the Foreign Secretary say:

    present indicative

    “Ich muss handeln!”

    “I have to act!”

    When you go to report on her statement in your article, you might report this statement using one of the statements below:

    present subjunctive I

    Die Außenministerin sagte, sie müsse handeln.

    The Foreign Secretary said she has to act.

    Die Außenministerin sagte, dass sie handeln müsse.

    The Foreign Secretary said that she has to act.

    Because it’s not a direct quote and because you’re writing, you’ll use the subjunctive I. There are two important things to note:

    • The tense of the original quote is preserved: present indicative → present subjunctive I. If the original quote contained the past tense, then you might use the past subjunctive I instead.

    • Why are there two versions of the reporter’s sentence? There are two versions because the conjunction dass(that) is optional in German just like in English. Both versions are common. The only thing to be careful of is the word order — as with other subordinate clauses in German, the addition of the conjunction “kicks” the conjugated verb (in this case müsse) moves to the end of the sentence.

    When to avoid using the subjunctive I in reported speech?

    Though the subjunctive I is commonly used in written indirect reported speech, there are two main contexts where you should avoid using this form of the verb:

    • In everyday spoken German, you’re more likely to use the subjunctive II in indirect speech. In some casual contexts you might even hear the indicative!

    • When first or second person subject (I, you, we) said, the subjunctive I is also uncommon. Germans prefer one of these options instead:

      • würde(would) + infinitive

      • subjunctive II

      Using these other forms helps to better distinguish the subjunctive form from the indicative form.

    What are other uses of subjunctive I in German?

    In addition to being used in reported speech, the subjunctive I can also be used to give commands, directions or instructions in writing. You can find this in:

    • Recipes and cookbooks:

      Man nehme 200g Mehl und 50g Zucker und verrühre beides gut.

      Take 200g flour and 50g sugar and mix well.

    • Technical language (e.g., mathematics or instruction manuals):

      Hier sei eine Zahl größer als 20…

      Let’s take a number bigger than 20…

      lit. Here is a number bigger than 20.

    • Historic/religious context, fiction:

      • Es lebe die Königin!

        Long live the Queen!

      • Möge die Macht mit Euch sein!

        May the force be with you!

    What are some idioms and phrases using subjunctive I in German?

    In German, a few idioms and set phrases always use the subjunctive I. Two of the most common ones are:

    • es sei denn(unless):

      present subjunctive I

      Paul wird morgen wandern gehen, es sei denn es regnet.

      Paul is going to go hiking tomorrow unless it rains.

    • so sei es(so be it):

      present subjunctive I

      “Neun Gefährten. So sei es. Ihr bildet die Gemeinschaft des Rings!”

      “Nine companions. So be it. You shall be the fellowship of the ring!"

    Summary

    In this post, we’ve introduced you to the German subjunctive I. Here are the important points to remember:

    • The subjunctive I is used primarily for indirect reported speech, specifically in written language (e.g., in news reports)

    • Use the same tense in the subjunctive I that the original quote used: present, past, future and future perfect. The tenses that are most frequently used in the subjunctive I are present and past.

      • Present → Looks mostly like the present indicative, but the “you” and “he/she/it” forms have e’s added

      • Past → Formed using the present subjunctive I of haben/sein + past participle

    • You will rarely ever hear the subjunctive I in spoken German, the subjunctive II is much more common there.
